Circuit and method for switching off a vehicle electric source

摘要

The circuit arrangement for switching off the accumulator system (1) has two switching elements (2,3), which are fitted in the vicinity of the accumulator system. The two switching elements in the event of a fault carry out an all pole switch off, so that with a fault both switch elements are opened. One of the two switching elements (3) represents the operating switch, by means of which the accumulator system can be switched off in a normal operating mode.
